The EPA’s Clean Air Act requires NAAQS (National Ambient Air Quality Standards) for six principal pollutants, called “criteria pollutants,” that are common in outdoor air, considered harmful to public health and the environment, and come from numerous and diverse sources. The Clean Air Act requires the EPA to review the standards—and the science behind them—periodically to determine whether changes are warranted.
The U.S. Environmental Protection Agency (EPA) issued a proposed rule to strengthen the primary (health-based) annual National Ambient Air Quality Standards (NAAQS) for fine particle pollution, PM2.5. Specifically, the EPA is proposing to revise the primary annual standard from 12.0 µg/m3 to a value within the range of 9.0 and 10.0 µg/m3.
Ethan Howland reports in Utility Dive that in a move that could add to regulatory requirements for coal-fired power plants, the Environmental Protection Agency on Friday proposed tightening the primary annual air quality standard for fine particulate matter, called PM 2.5, to a range of 9 micrograms per cubic meter to 10 µg/m3 from 12 µg/m3. Coal plants owners in nonattaintment areas for a revised standard will have to meet requirements outlined in any approved state plans for meeting the federal PM 2.5 limit, according to Julia Criscuolo, ESAI Power manager of renewables and emissions.
